Patent CA-2238094-A1 (CA)
Title: Blow molded container having paneled side wall
Inventor: DARR RICHARD C
IPC: B29C49/04
Filed: 1996-12-18
Abstract: A plastic blow molded container (10) of polyethyl-ene terephthalate has a side wall ( 18) at least three verti-cally spaced horizontal ribs (38) of an annular shape and at least 12 vertical ribs (40) spaced circumferentially and extending between the horizontal ribs to cooperate there-with to define generally rectangular panels (42) that are capable of flexing inwardly to accommodate for shrink-age upon cooling. The construction of the container al-lows it to have a lightweight construction according to the equation: W G < 12G + 34V G wherein W G is the weight in grams of the container, 12G is 12 grams, and 34V G is a weight in grams that is 34 times the internal volume of the container in liters. The horizontal ribs (38), the vertical ribs (40), and the rectangular panels (42) are constructed and positioned to facilitate label ap-plication to the container side wall (18).
Patent CA-2238264-A1 (CA)
Title: Abrading material
Inventor: YOUNG MICHAEL
IPC: D04B1/04
Filed: 1996-11-21
Abstract: A method of making an abrading sheet material preferably comprises knitting a ground structure comprising a polyester yarn and a shrinkable polyolefin yarn with laid-in looped threads of a hard material, such that the looped threads are raised from a surface of the ground structure, and shrinking the shrinkable yarn of the ground structure to grip the looped threads to lock the loops in place in the ground structure. Preferably the polyolefin yam is heat shrinkable, and the method comprises the step of heat treating the ground structure so that the polyolefin yarn in the ground structure contracts to grip the looped threads to lock the loops in place, while simultaneously restraining the ground structure against shrinkage. The invention is also a method of making a scouring pad comprising the step of heat bonding or welding abrading sheet material as described to a backing of a suitable resilient thermoplastic material, e.g. by impulse heat welding.
Patent CA-2239852-A1 (CA)
Title: Timing reference for scheduling data traffic on multiple ports
Inventor: STERNE JASON T
IPC: H04L12/56
Filed: 1998-06-08
Abstract: Data traffic such as cell streams in an ATM communication network frequently contain data destined for multiple output ports having different transmission data rates.

Patent CA-2240869-A1 (CA)
Title: Grain cart drive assembly
Inventor: ALLAN RONALD
IPC: B60P1/42
Filed: 1998-06-17
Abstract: In a grain cart equipped with a lower horizontally-disposed input drag auger, a vertically disposed lift auger, and an upper horizontally disposed discharge auger, a unique drive train is used. The lift auger and the discharge auger can be activated independently of the input auger in order to empty their contents on start-up of the grain cart discharge system. By so doing the strain on the drive train is considerably lessened thus permitting very large grain carts to be emptied without damage to the drive train system. A hydraulic cylinder activates a belt-tightener between a drive sheave and a driven sheave. The driven sheave is attached to the axis of the drag auger. When the hydraulic cylinder is extended, pressure exerted on the belt causes the input auger to rotate and to feed the lift and discharge augers.

Patent CA-2241248-A1 (CA)
Inventor: WILKE RAUD A
IPC: G05D7/01
Filed: 1997-09-30
Abstract: An improved pressure-compensated hydraulic system for feeding hydraulic fluid to one or more hydraulic actuators (20). A remotely located, variable displacement pump (16) provides an output pressure equal to input pressure plus a constant margin. A pressure compensation system requires that a load-dependent pressure be provided to the pump input through a load sense circuit.  A reciprocally spooled, multi-ported isolator transmits the load-dependent pressure to the pump input but prevents fluid in the load sense circuit from leaving the load sense circuit and flowing through a relatively long conduit leading to the remotely located pump. In a multi-valve array (12), at least one valve section (13, 14, 15) has a backflow-preventing shuttle valve which prevents backflow through the pressure compensation system if a main relief valve is operative.

Patent CA-2251458-A1 (CA)
Title: Inserted lid, box with inserted lid, and process for the production of the lid
Inventor: GRABHER WERNER
IPC: B65D43/02
Filed: 1998-10-23
Abstract: An inserted lid (1) for a box (2) is formed so that a contact region (5) can be pressed against the inside of the side wall of the box. In the non-inserted state, said side wall is slightly larger than the box opening (4). on insertion of the lid (1) into the box (2), the largest circumferential line of the contact region (5) must fit the inside of the side wall of the box as a result of an elastic deformation of the closure surface (3). To prevent the forces emanating on insertion from the side wall of the box from leading to irreversible deformations, the closure surface (3) has spring properties which are radial with respect to the contact region (5) and permit an elastic deformation of the contact region (5) in the radial direction. To ensure these spring properties, the closure surface (3) has a shape differing from a flat surface, in particular two concentric waves (7) formed constant distances away from the contact region (5) and/or a central vault (8). On insertion of the lid (1), this difference is slightly increased by the compression of the contact region (5), or the waves (7) and the vault (8) are slightly deformed, which leads to storing forces which press the contact region (5) against the inside of the side wall of the box. Owing to the shape imposed on the closure surface (3) , it is ensured that no creases or other irreversible deformations form on insertion of the lid (1) .

Patent CA-2257298-A1 (CA)
Title: Non-uniform time scale modification of recorded audio
Inventor: COVELL MICHELE
IPC: G10L21/00
Filed: 1997-05-12
Abstract: To modify the temporal scale of recorded speech, relative stress and relative speaking rate terms are computed for individual sections, or frames, of the speech. These terms are then combined into a single value denoted as audio tension. For a nominal time-scale modification rate, the audio tension is employed to adjust the modification rate of the individual frames of speech in a non-uniform manner, relative to one another. With this approach, compressed speech can be reproduced at a relatively fast rate, while remaining intelligible to the listener.

Abstract: A currency handling system adapted to accommodate currencies of any denomination or type without having been pre-programmed with data representative of the denominations or types. The currency handling system is capable of generating such data internally, by scanning sets of master currency bills to obtain information representative of the master bills which may be used to denominate or authenticate subsequent test bills according to selected or default sensitivity levels. The master currency bills may comprise bills of different currency types, including bills from different countries. The master information may comprise numerical and/or non-numerical data. The denomination or authentication of the test bills is based on a comparison of either pre-stored or self generated master information with scanned data values associated with the test bills. Master information derived by one machine may be quickly and efficiently loaded into one or more secondary machines through a flash card loading system,
